15. HOW TO KEEP THE MACHINE IN GOOD REPAIR
(1) Oiling
Oiling is so important that if you should be negligent in this respect you would
not only shorten the machine’s service life bLt also could cause it to become out
of order.
Do not use too much oil. It is not only unnecessary but may stain or soil the
material.
(2) Where to Oil
(a) The arrows indicate those parts
to be oiled.
(b) Just one drop at a time will do.
(c) When you have oiled those parts
indicated run the machine for a
while slowly so that the oil can
Fig. 21 TOP & BOTTOM
penetrate and spread itself.
(3) The Quality of the Oil Used
Oil of poor quality will not only cause
the machine to run heavily but also
will cause wear and tear of the unit.
Use only good quality oil refined for
use on sewing machines. 15
Fig. 22

16. HOW TO MAKE BUTTON HOLES
Place a marking needle
across the cutting
space to protect the
stitching.
i. Lcemove the regular presser foot and attach the buttonhole foot.
2. Set the zigzag width lever between “1” and “2’.
Set the stitch length regulator knob to obtain close stitches (stain stitch).
3. Mark with a pencil or chalk the position and exact length of the buttonhole on
the fabric.
4. Lower the needle carefully into the mark on the fabric indicating the beginning
of buttonhole.
Lower the presser foot and commence sewing the left row of the buttonhole until
it reaches the end of the marking. (1)
Stop the machine with needle on fabric at point A.
—16—

5. Lift the presser foot and using the needle as a pivot, turn the fabric end for
end to bring the buttonhole to position (2).
6. Raise needle from fabric and drop the feed teeth by setting the drop feed knob
at “0”.
7. Set the zigzag width lever at “4” and sew three or four stitches to make bartack.
(2)
8. Raise needle from fabric, also raise feed teeth by setting the drop feed knob
at “2”.
9. Now to sew the other row of the buttonhole, return the zigzag width lever be
tween “1” and “2” (to its original setting) and commence to sew until your
stitching reaches the position shown in figure (3).
10. To make the final bar-tack, again setting the drop feed knob at “0” and sew the
bar-tack. (4)
11. Return zigzag width to “0” and take two or three stitches to fasten bar
threads and prevent ravelling.
12. Remove fabric from the machine and open the buttonhole with a buttonhole cutter
or seam ripper.

17. DARNING AND EMBROIDERY
Raise the presser bar lifter and remove the presseL foot. Then lower the presser
bar lifter to ensure the thread teision device is set correctly.
Set the drop feed knob at “0”.
Now your machine is ready for embroidery and darning.
Embroidery will be done most successfully when the fabric is stretched and fixed in
an embroidery hoop. Hold the hoop closely on the machine bed with both hands, press
the material with your left forefinger in the vicinity of the needle.
This will help in holding down the material and will prevent the machine from
making skipped stitches. Manipulate work carefully and be sure to keep fingers out
of the path of the needle.
Adjust thread tensions for the best appearance of embroidery work and slightly in
crease the bobbin thread tension to avoid the lower thread from being pulled up.
